Why Your Moon Cactus Is Dropping Leaves: Causes and Solutions

If your Moon Cactus is dropping leaves, it can be concerning. This vibrant, colorful cactus is popular for its unique appearance, but leaf loss can indicate underlying issues. Understanding the causes and solutions can help you revive your plant and keep it healthy.

Common Causes of Leaf Drop in Moon Cactus

1. Overwatering

Moon Cacti are succulents that store water in their stems. Overwatering can lead to root rot and stress, causing leaves to drop. Ensure the soil dries out completely between waterings.

2. Underwatering

While they are drought-tolerant, prolonged periods without water can also cause leaf loss. Keep a consistent watering schedule, watering only when the top inch of soil feels dry.

3. Insufficient Light

Moon Cacti thrive in bright, indirect sunlight. Lack of adequate light can weaken the plant, leading to leaf drop. Place your cactus near a sunny window for optimal growth.

4. Temperature Stress

Extreme temperatures, either too hot or too cold, can cause stress. Keep your Moon Cactus in a temperature range of 65-80°F (18-27°C) and protect it from drafts and frost.

Solutions to Prevent Leaf Drop

Adjust Watering Habits

Water only when the soil is dry, typically every 2-4 weeks. Use well-draining soil and ensure the pot has drainage holes to prevent water accumulation.

Provide Adequate Light

Place your Moon Cactus in a spot with bright, indirect sunlight. If natural light is limited, consider using a grow light to supplement.

Maintain Proper Temperature

Avoid exposing your cactus to cold drafts or direct heat sources. Keep it in a stable environment within the recommended temperature range.

Check for Pests and Diseases

Inspect your plant regularly for signs of pests like mealybugs or scale. Treat infestations promptly with insecticidal soap or neem oil. Remove any affected parts to prevent spread.

When to Seek Professional Help

If your Moon Cactus continues to drop leaves despite adjustments, consider consulting a plant specialist. Persistent issues may require more specific treatment or soil testing to identify underlying problems.
